Detailed Description

template<typename Main, typename Aux, typename CollProxy, typename Tag = Aux, typename AuxColl = std::vector<Aux>>
class proxy::ParallelDataProxyMaker< Main, Aux, CollProxy, Tag, AuxColl >

Creates an associated data wrapper for the specified types.

Template Parameters

Main	type of main datum (element) to associate from ("left")
Aux	type of datum (element) to associate to ("right")
CollProxy	type of proxy this associated data works for
Tag	tag for the association proxy to be created
AuxColl	type of the auxiliary data (default: `std::vector<Aux>`)

This class is (indirectly) called when using proxy::withParallelData() in getCollection(). Its task is to supervise the creation of the proxy to the auxiliary data parallel to the main data type. The interface required by withParallelData() includes:

a static make() method creating and returning the auxiliary data proxy with arguments an event, the main data product handle, a template argument representing the main collection information, and all the arguments required for the creation of the associated proxy (coming from withParallelData()); equivalent to the signature:
template <typename Event, typename Handle, typename MainArg, typename... Args>
auto make(Event const&, Handle&&, MainArg const&, Args&&...);

This class can be specialized (see withParallelData() for an example). The default implementation just wraps a one-to-many std::vector<Aux> data product fulfilling "parallel data product" requirement (see the "Definitions" section in ProxyBase.h documentation).

The last template argument is designed for specialization of auxiliary data in the context of a specific proxy type.
